TRACTION-WHEEL.

EPEGIFIGATIOLI formingpart of Letters Patent No. 734,608, dated July 28, 1903. Application filed December 24. 1901. Serial No. 87,125. (No model.)

To al whom it Inay concern.-

, Be it known that I, HENRY H. PORTER, J r.,-a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Traction- Wheels, (Case No. 3,) of which the following,

taken in connection with the accompanying drawing, is a specification.

to This invention has reference to the provision of a wheel having two tread portions, one constructed to run upon a smooth surface or fioor and the other, flanged or otherwise, capable of running upon a rail or ordinary I 5 railroad-track.

One object of my invention is to provide a wheel of the type specified which can be used in conjunction with merchandise-transfer cars or trucks for service upon a traction-floor in conjunction with some railroad-track connected with said traction-floor,whereby goods may be taken from any point adjacent to 'said floor by means of said track or rail toany other point which may be desired; but I do not wish to be understood as limiting my,

claims in this regard.

In carrying out my invention I have provided a construction which I have shown in preferred form in the accompanying d rawing,

in whichbolts 6 or other suitable attaching devices, I

' face.

have secured a rim 7, formed with a tread portion 8, which constitutes, in effect, an expansion -or a widening of the crown of the flange 5, so as to make a suitable hearing for use on a traction-floor or other smooth sur- The rim 7 may be made removable in case it should be desired at any time to take it off from the wheel 2 and, if desired, can be then suspended under the truck, so as to clear the track.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A car-wheel provided with a tread-surface, a guard-flange to engage the rail, and an extended floor-tread level with said flange and placed on the side thereof, and fitting the contour of said flange.

2. A car-wheel having a rail-tread, a guardflange for the rail, a second tread-surface in line with said flange and supported against the same and against an abutment upon the wheel-rim. I

3. A wheel havinga tread portion constructed to run on a rail, a flange to guide it on said rail, and a removable tread portion, attached to said wheel. 7

In Witness whereof I have hereunto set my hand in the presence of two s'ubsci'ibin witnesses.
